PSP Online?

Hey everyone this is my first post. I have been reading alot of threads here before I signed up. Looks like you have alot of good people who know alot of things. Anyhoo heres my question. I am running 3.03OE-C and have alot of games on ISO that I was looking forward to playing online (Metal Gearortable Ops, Madden07, Need For Speed Carbon, Medal Of Honor, Tekken Dark Ressurection, Call Of Duty, ect, ect) I was wondering if my custom firmware is somehow blocking online play because whenever I go into infrastructure mode I cant find anyone online. Or could it be a faulty internet connection? Any help would be appreciated. Thanks

Im having the same trouble, I ripped my Midnight club from UMD to ISO on me memory stick and i tried to play with me girlfriend (she had the UMD) and it kept saying I had disconnected or my psp locked up.
